“…Comparing the weight loss results of Zn-Co alloy coatings with those of pure zinc and other zinc based alloy electrodeposits reported in previous studies [6,7], it can be said that Zn-0.6% Co coatings showed superior wear resistance than zinc coatings sliding against stainless steel ( Fig. 4(b)).…”

“…The main wear mechanism was found to be the extensive plastic deformation and shearing of the coating. In the latter study [7], they observed that the friction coefficient and the weight loss of zinc-14 wt.% nickel coatings sliding against alumina counter material were higher than those against stainless steel. Lovell and Deng [8] investigated the nature of interfacial friction of zinc and lead coatings on steel substrates in stamping operations, by means of a tensile strip testing system.…”

“…Panagopoulos et al [6,7] studied the sliding wear behaviour of zinc-iron and zinc-nickel alloy electrodeposits. In the former study [6], they observed that the friction coefficient and wear volume of zinc and zinc-iron electrodeposits sliding against stainless steel counter spheres decreased with increasing iron content of the coatings.…”

“…The composite coatings of single metal and alloy have been developed for improved material properties with regard to corrosion stability; wear resistance, friction coefficient, self-lubrications, high temperature stability, electrical contacts and improved catalytic activity [1][2][3][4][5]. The composite based on Zn-Ni are finding increased interest in surface technology and corrosion protection, as they possess improved material properties.…”

“…They showed that the zinc coating has a friction coefficient greater than that of the steel substrate, while the zinc coating with ash has a friction coefficient lower than that of the steel substrate. The authors of another paper have studied the sliding wear behavior of Zinc and Zn-Co alloy electrodeposits and they made a conclusion that the friction coefficient of zinc is higher than the friction coefficient of Zn-0.6% Co and Zn-4% Co, but the wear rate is lower for the zinc than for the alloys [6]. They also concluded that the wear mechanism was found to have plastic deformation and shearing of the coatings surface layers.…”

Three coatings of decorative chromium, hard chromium and zinc, electrolytically deposited on the C45 steel substrate, are considered in this study. Experimental characterization of the tribological response of the substrate and different coatings against spherical 100Cr6 counterbody is developed with a linear reciprocating tribometer. The results show that the three coatings have similar values for the stabilized coefficient of friction which remains substantially higher than the value of the friction coefficient for the substrate. The decorative chromium coating has the lowest wear resistance. A better wear resistance is obtained with the zinc coating. The first place in terms of wear resistance is occupied by the hard chromium coating and the uncoated substrate which have similar resistance. Keywords: coatings; substrate; electrolytic; chromium; zinc; friction; wear.The term "surface treatments" means all operations: mechanical, chemical, electrochemical or physical which affect the appearance or structure of the material surface to suit the operating conditions data. Surface treatments are variable and can improve the optical properties or appearance, resistance to wet or dry corrosion, thermal or electrical conductivity, response to friction, wear resistance. Treatments such as chromium, zinc, aluminum coatings are now widely used in many industrial and domestic sectors. Treated surfaces may be the seat of the phenomena of friction and wear in case they are in contact with a rigid counterbody. This may cause local fracture of the coating and therefore the activation of the corrosion phenomenon. The response of tribological coatings of chromium electrodeposited on a mild steel substrate was studied in [1]. The authors showed that the coatings have better wear resistance than the uncoated substrate. The wear behavior of electrolytic hard chromium (EHC) and arc PVD CrN coatings under lubrication was investigated in [2] and the researchers concluded that the friction coefficient of EHC is higher than the friction coefficient of CrN but the wear resistance of EHC is lower than that of CrN. The tribological behavior of EHC coatings sliding against ceramic and steel counterparts was investigated in [3]. They showed that in the case of steel ball as a counterbody the wear mechanism of EHC can be divided into three stages: adhesion and formation of debris; formation of abrasive particles and abrasive wear and dominance of abrasive wear. Other researchers have investigated the mechanical and tribological properties of EHC and HVOF (High Velocity Oxy-Fuel) to prove that EHC cannot form a smooth tribofilm [4]. Under high contact pressures this film is easily fractured and partly removed. Therefore EHC coatings undergo higher mass losses and develop higher friction coefficient than the HVOFsprayed coatings in the same conditions. Some other researchers have studied the friction response of electrodeposited coatings of zinc and zinc with ash deposited on the mild steel substrate [5]. They showed that the zinc coating has ...
